  • a trigger or other mechanism may be used to actuate the valve, with liquid in the can being propelled through a nozzle.
  • aerosol dispensers may suffer from leakage and/or inadvertent dispensing.
  • triggers may inadvertently be actuated when handling or transporting aerosol spray paint cans, resulting in unwanted dispensing of paint.
  • many such dispensers are limited in the manner in which liquid is dispensed, for example such as limiting a pattern in which paint is sprayed from an aerosol spray paint can.
  • Various example embodiments are directed to locking spray nozzle apparatuses and methods, which may address various challenges including those noted above.

  • aspects of the present disclosure are believed to be applicable to a variety of different types of apparatuses, systems and methods involving dispensing of liquid, such as for dispensing aerosols from pressurized containers.
  • Various embodiments are directed to an apparatus having selectable nozzle apertures and a related locking (or blocking) mechanism that operates to lock and unlock the apparatus for spraying applications.
  • a rotatable dial has multiple nozzles and features/cogs that operate to limit or prevent actuation of a trigger mechanism to positions in which the nozzles are aligned for dispensing liquid. While not necessarily so limited, embodiments are characterized in this context.
  • an aerosol spray cap has multiple spray nozzles coupled to a rotatable structure such as a dial or disk.
  • the rotatable structure operates to selectively align each of the spray nozzles to a channel for receiving and spraying propelled liquid.
  • the spray cap includes an actuator such as a trigger or button coupled to move with the rotatable structure, and which operates to dispense propelled liquid when actuated.
  • the rotatable structure and body of the spray cap have mechanical features that interact to limit movement of the actuator such that the propelled liquid is prevented from being dispensed when one of the spray nozzles is not aligned to the channel.
  • the disk may employ a gear and tooth mechanism with gears aligned with the nozzles and a tooth on the cap such that the actuator is allowed to move when one of the gears is aligned to mesh with one of the teeth.
  • the gear is configured relative to the nozzles such that such alignment occurs only when one of the nozzles are aligned to the channel.
  • the gear does not mesh with the tooth, and the tooth prevents movement of the gear (and actuator) in a direction toward the tooth.
  • Such a position may effect an “off’ or “shipping” position in which the spray cap is inoperable for dispensing liquid.
  • the spray nozzles are located at respective angular positions around the rotating structure, with a gap between the spray nozzles.
  • the mechanical features may be located such that movement of the actuator is limited when the rotating structure is rotated so that a position between two of the nozzles is aligned with the channel, and such that the actuator is allowed to dispense the propelled liquid when one of the nozzles is aligned to the channel.
  • the propelled liquid may thus be dispensed via movement of the actuator (and rotatable structure) only when one of the nozzles is aligned to the channel.
  • the actuator button may be pivoted from a location opposite to the location of the disk (relative to the actuator button). Pivoting the actuator button may also result actuation of the disk, such as by depressing the disk vertically and/or pivoting the disk. As such, when one of the nozzles is aligned to the channel and force is applied to the actuator, propelled liquid may be dispensed through one of the nozzles. When the disk is rotated such that a position between the nozzles is aligned to the channel, the disk prevents pivoting of the actuator and depression of the disk, preventing dispensing of the propelled liquid.
  • the actuator when coupled to a spray canister such as a spray paint can having a valve, the actuator may be implemented as a button that, when actuated, opens the valve and allows fluid from the spray canister to spray through the channel to a nozzle in the disk that is aligned to the channel.
  • Another embodiment is directed to an apparatus having a liquid supply channel, a rotatable dial, an actuator and a locking mechanism.
  • the rotatable dial has a plurality of nozzles, separated from one another by a portion of the rotatable dial, and is operable to align each of the respective nozzles with the channel for receiving and spraying propelled liquid received via the channel.
  • the apparatus may include a sleeve coupled to the channel and actuator, with the rotatable dial having a shaft coupled to the sleeve and configured to rotate within the sleeve.
  • the actuator is operable to release the propelled liquid into the channel by actuating a valve.
  • the locking mechanism operates with the rotatable dial to prevent actuation of the valve and block delivery of the propelled liquid to the channel, by preventing movement of the actuator when the rotatable dial is positioned so that the nozzles are not aligned with the channel.
  • the locking mechanism further operates with the rotatable dial to allow the actuator to move for actuating the valve and delivering the propelled liquid to the one of the nozzles via the channel, when the rotatable dial is positioned with one of the nozzles aligned with the channel. Accordingly, the locking mechanism may operate to prevent unwanted dispensing of liquid, for instance while rotating the dial for aligning a nozzle having a particular size or while stored or shipped.
  • the actuator may be implemented in a variety of manners.
  • the actuator includes a button mechanism, such as a spray button for a spray can, which opens the valve when depressed with the rotatable dial positioned such that one of the nozzles is aligned with the channel.
  • the locking mechanism thus facilitates the movement of the actuator when the nozzle is so aligned.
  • the button mechanism, dial and channel may be coupled and move together in response to depression of the button.
  • a pivot structure is coupled to the button mechanism and operates to facilitate movement of the actuator by pivoting the button mechanism about the pivot structure, therein actuating the dial and channel (e.g., downward to dispense propelled liquid from a canister).
  • the locking mechanism includes a mechanical stop and a gear coupled to rotate with the dial (or the gear may be part of the dial).
  • the gear has cogs and recessed regions between the cogs located relative to the nozzles and the mechanical stop, so that one of the cogs is aligned to the mechanical stop and prevents the button from pivoting to actuate the valve when the rotatable dial is positioned with the nozzles out of alignment with the channel.
  • the rotatable dial is positioned with one of the nozzles aligned with the channel, one of the recessed regions is aligned for meshing with the mechanical stop, which allows the button to pivot about the pivot structure and actuate the valve for delivering the propelled liquid to the one of the nozzles via the channel.
  • the cogs may include a cog corresponding to each space between adjacent ones of the nozzles, such that one of the cogs is aligned to the mechanical stop at all instances in which space between any adjacent ones of the nozzles is aligned to the channel.
  • One of the recessed regions may further be aligned to mesh with the mechanical stop for allowing movement of the button for actuating the valve at all instances in which one of the nozzles is aligned to the channel.
  • the locking mechanism includes a mechanical stop and a gear coupled to rotate with the dial.
  • the gear operates with the mechanical stop to prevent actuation of the actuator when the nozzles are not aligned to the channel.
  • the gear may include a recessed region configured to mesh with the mechanical stop.
  • the locking mechanism may include a pivot arm coupled to the actuator. The pivot arm operates with the cog and gear to actuate the valve when the recessed region is meshed with the mechanical stop.
  • the apparatus may include the valve and a liquid container coupled to the valve.
  • the liquid supply channel, rotatable dial, actuator and locking mechanism may be part of a cap coupled to the container.
  • the cap may operate to spray liquid from the container through one of the nozzles in response to the actuator being depressed, when the nozzle is aligned to the channel, by actuating the valve and therein causing the container to propel liquid through the valve, channel and nozzle.
  • the button may be coupled to a pivot and further be operable to actuate the valve in response to force applied to the button that causes the button to pivot and depress the channel, dial and valve vertically. This depression causes the propelled liquid to be dispensed when the rotatable dial is positioned with one of the nozzles aligned with the channel.
  • the channel, dial and actuator may be coupled to a pivot and operable to actuate the valve in response to force applied to the actuator, which causes the channel, dial and actuator to rotate about the pivot when the rotatable dial is positioned with one of the nozzles aligned with the channel.
  • Another embodiment is directed toward a nozzle apparatus having a channel, an actuator, a mechanical stop, and a dial having nozzles and a gear.
  • the dial is operable to rotate for selectively aligning each of the respective nozzles with the channel.
  • the gear has a plurality of cogs and recessed regions between adjacent ones of the cogs, and operates with the mechanical stop to prevent movement of the actuator when the dial is positioned such that none of the nozzles are aligned with the channel.
  • the gear may be operable to mesh one of the recessed regions with the mechanical stop to facilitate movement of the actuator when the dial is positioned with one of the nozzles aligned with the channel.
  • Such an apparatus may be useful, for example, to prevent unintentional actuation and therein prevent unintentional dispensing of fluid via the nozzles.
  • the nozzle apparatus may be implemented in a variety of manners.
  • the cogs may be aligned relative to the nozzles so that one of the recessed regions is aligned to mesh with the mechanical stop and therein facilitate movement of the actuator, when one of the nozzles is aligned to the channel.
  • the actuator may include a button that is part of a pivot arm coupled to a pivot point, with the pivot arm being operable to pivot about the pivot point in response to pressure applied to the button when one of the recessed regions is aligned to mesh with the mechanical stop.
  • the nozzle apparatus may include a fluid container and such a valve coupled to the actuator for dispensing fluid from the container into the channel, in response to movement of the actuator. For instance, paint may be dispensed from the fluid container, in response to depression of a button as noted above, which causes downward movement of the actuator and opens the valve.
  • the dial of the nozzle apparatus operates to selectively align each of the respective nozzles with the channel for receiving and spraying propelled liquid received via the channel.
  • the actuator operates to release the propelled liquid into the channel by actuating a valve.
  • the gear and mechanical stop form a locking mechanism that operates with the dial to prevent actuation of the valve and block delivery of the propelled liquid to the channel, by preventing movement of the actuator when the dial is positioned with the nozzles out of alignment with the channel.
